How to read the ratings
The ratings are updated live as new participants add their grades to the system. Rating bar consists of the following elements:
- Device or technology being tested.
- Value of actual perceived audio quality (rating) which is also indicated by a bar length
. Anchor points could be interpreted as follows:
In most cases using this device/technology:
1.0 – you will hear heavily distorted sound
2.0 – you will hear unpleasant sound artifacts
3.0 – you will hear distinctly audible but tolerable sound artifacts
4.0 – you will hear faintly discernible sound artifacts
5.0 – you will not hear any sound artifacts
above 5.0 – all sound artifacts will be beyond threshold of human perception with corresponding perception margin
and
- The high and the low of a rating. As each device is tested under nine different sound items, there are nine different local ratings for a device. In fact, the actual rating
is an average of those nine local ratings. The highest and the lowest ones are indicated. Big gap between them means that sound quality of device/technology is not consistent enough. It will vary with type of sound material: music of different genres and complexity, voice with or without music, noisy/clear recordings etc. The lowest local rating is more important in this sense as it indicates worst case behavior of tested device.
- Reliability of rating. It is also indicated by the color of bar - more reliable ratings have less percentage values and darker bars. Reliability depends on number of grades returned by participants. In most cases 5% or less is OK.
- Ruler for convenient measuring of highs and lows.
